我的下载文件概念如下： 如果适配器在早上7点重新启动，则 首次下载将从00:00:00开始至早上7点。 5分钟后会再次下载，下载时间也是6.58am到7.05am。 Timezome会有所不同，如亚洲/新加坡，亚洲/香港等。 但出于某种目的，这个时区需要转换为GMT。
以下是我的编码

我用例子来表示我的问题： 当适配器在新加坡时间的2017-02-18 7am重新启动时，转换为GMT后的开始时间为2017-02-18 00:00:00，但结束时间为2017-02-17 11:50:34。 这是错误的..
当适配器在2017-02-18上午8点之后重新启动时，新加坡时间，转换为GMT后开始时间为2017-02-18 00:00:00，但结束时间为2017-02-18 00:05： 34（最多转换为GMT的时间）。但这是正确的..
如果我没有转换为GMT，所有时间都是正确的，但我不想这个答案，因为它会影响一些数据，所以它需要先转换为GMT。
请告知我的编码错误...
谢谢
